As you know, the "in the room" tone has been the subject of many many internet discussions.
Basically, how can a digital device sound like a real tube amp sitting right in front of you?
And the conclusion seems to be that it can't if you're using "FRFR" because it will sound like a real tube amp with a mike in front of it.
Well, I think the Kemper puts that one to rest once and for all.
Kemper (cabs OFF) into poweramp and cabinet loaded with guitar speakers is exactly like playing a tube amp...it's the "in the room" tube amp tone.
Agree, disagree?
